I'm looking to present the girlfriend with a custom game, preferrably with lots of red hearts, and cute little animals. I'm a programmer, and can make my way around compiling and coding, in multiple langauges.
So, can anyone here recommend games that meet the criteria (cutish/romantic and open source). I'm looking to simply modify the text dialog a little and make a customized version to present to her.

While a game written in LOVE would be nice, I'm also open to other engines if anyone knows of these.
Cheers.
PS: I'm currently looking at project Hawkthorne, as a big community fan.
